Benefits of a Sound Machine

A sound machine may be a lifesaver if you spend your nights humming, singing and gently shushing your baby in an attempt to coax them to sleep. Using a machine can help ease that load and give you a chance to get your own much-needed rest.

The extra noise may be especially comforting to newborns who are accustomed to hearing up to 90 decibels of sound in the womb. The sounds of their mother’s heart beating and the whoosh of blood rushing through her vessels are constant in utero, and a new baby may find the quiet of the outside world to be a stark and jarring contrast.

Particularly if you have older children or noisy pets, a sound machine can also be a great help in masking other household noises. Having some background noise playing in your baby’s room can help ease that feeling of having to walk on eggshells during nap time.

What Kinds of Sounds do Babies Prefer?

Most of the choices a sound machine offers are relaxing for babies and adults alike.

Nature Sounds – Soft rainfall, a babbling brook or waves hitting the shore are commonly offered on most sound machines. Hushed tones of bird or insect noises can be other nature sounds.

Gentle rhythmic tones – Very young babies may also enjoy this noise that mimics the sound of their mother’s heartbeat.

Soft instrumental music – Babies may find songs with vocals too stimulating to be conducive to sleep. Classical pieces or lullabies are typically favorites.

White Noise – White noise refers to sounds that consist of just one frequency and are easy for the brain to become accustomed to. Fans and radio static are two common sources of white noise.

Features To Look For

Simple Controls – Choosing a machine that is designed with large, easy-to-use controls can save you the trouble of fumbling in the dark with finicky knobs or switches.

Built-in Nightlight – A sound machine that doubles as a nightlight can help you eliminate one other piece of nursery equipment.

Projector Feature – Some babies will enjoy looking at soothing images as they fall asleep.

Adjustable Volume – This one is really important. While you need a machine to be loud enough to do its job, a little one’s sense of hearing is still developing. Keeping noise at the right balance of effective and safe is essential.

Variety of Sound Choices – Some people prefer a model that only makes one type of noise, and there are several options that will do just that. You may find, however, that having multiple choices allows you to experiment and offers a few options if your baby doesn’t take well to the first one.

A Timer – If you want to use your sound machine only while your baby is falling asleep, this feature could take one thing off your mind by automatically shutting off at the pre-set time.

Multiple Power Options – If you plan to use your machine in various settings outside your baby’s room, a unit that offers battery, USB and AC power choices can be very convenient.

How to Use a Sound Machine

Your goal is to “cushion” the room with white or soothing noise. Sixty decibels should be adequate to provide an effective sound cover while still being firmly in the safe range.

You may need to try a few different settings to find the volume that your baby prefers and is loud enough to cover outside noise. Typically, you should aim for a noise level that is about equal to a normal conversational tone.

As another hearing safeguard, avoid setting up the sound machine too close to your baby’s ears. Select a place that is at least a few feet away from your child’s crib.

Turning the machine on while your child winds down for bed or their nap can also help ease the transition from playtime to sleep time.

Potential Concerns

Can the baby become dependent on using a machine?

The short answer is yes, it is possible that your baby could get to the point where they find it difficult to sleep without background noise.

Many parents feel the trade-off is worth it, however. Most sound machines are quite small and are powered by batteries or a standard electrical outlet, making them easy to transport.

It is also important to recognize that a current problem needs a timely solution. Caring for a baby requires a large amount of energy on the part of the caregiver, and you can only sacrifice so much sleep before you may begin to feel compromised as a parent.

Even if it is only a temporary solution, using a sound machine can make a big difference in the amount of rest you and your baby are able to get.

Can a sound machine cause any developmental delays?

Babies learn how to make a variety of sounds by hearing noises and then trying to imitate them. As long as you expose your baby to conversations, books, songs and other environmental sounds, using a sound machine while baby sleeps should not interfere with their development.

Can a sound machine damage a child’s hearing?

According to Johns Hopkins Medicine, noise levels less than 90 decibels are considered to be safe for children.

Adjustable volume controls also let you select your own preferred sound level.

Our Choices – a Closer Look at the Best Sound Machines

Marpac Dohm Classic

Pros

  • Excellent at masking ambient noises
  • Offers two speed settings along with pitch and volume control
  • Compact size fits anywhere and is easy to transport

Cons

  • The motor can collect dust that may cause a whining noise
  • Only one sound choice offered
  • No battery option

The Dohm Classic from Marpac does one thing and does it well.

This machine offers a single sound option that very effectively drowns out unwanted noises. Similar to the noise a fan makes, the Dohm features the classic Marpac sound of moving air. This could be a great option for parents who are looking for true white noise but may be leery of a fan blowing in their baby’s face.

Instead of digitally produced noise, the Dohm has a powerful motor that can be set to high or low speed with the flip of a simple switch. The outer shell contains holes that regulate airflow, and twisting the shell to open more or fewer holes allows you to adjust the pitch level as well as the volume.

The Dohm is a powerhouse in a small size, measuring 5.8 inches across and just over three inches high. With its compact design, you shouldn’t have any trouble finding a spot for the Dohm in any room you want to use it.

One concern with this model is its tendency to develop a whining or rattling sound over time. This problem seems to be caused by a build-up of dust around the fan mechanism in the motor compartment. Marpac does offer a one-year warranty on its products if you experience this issue.

Marpac Whish

Pros

  • Offers a nice mix of sound choices
  • Labeled buttons make it easy to pick the sound you want
  • Wide choice of volume settings

Cons

  • Can be hard to find the volume button in low light
  • Timer settings cannot be adjusted
  • Requires wall outlet

Another option from Marpac, the Whish offers a much wider selection of noise settings than the Dohm. While the Dohm uses an actual fan to produce sound, all the sounds offered by the Whish are electronically generated.

All settings on the Whish are controlled by push buttons. Each sound, the up/down volume and the timer have their own buttons on the unit’s top, while the power button is located on the front.

With sixteen sound options, it’s likely you will be able to find at least one you and your baby like. Choose from eight white noises, four nature sounds and four music/meditation sounds. Set a natural tone to help your baby relax before bedtime, then easily switch to white noise overnight.

The Whish offers a great range of volumes, with the highest setting being a bit louder than some other machines offer. This could come in handy when you have friends over during your baby’s nap time or after bedtime.

A timer feature allows you to set the Whish to run for either six or eight hours. Unfortunately, if you want the Whish to turn off before six hours, you will need to manually turn it off.

Homedics MyBaby SoundSpa Lullaby

Pros

  • Small and lightweight design
  • Has a light projector feature that can double as a nightlight
  • Plays nature sounds and lullabies

Cons

  • You have to scroll through all the sounds to select the one you want or to turn the unit off
  • Images are only projected directly overhead with no adjusting option

With push-button controls that allow you to choose sounds, set a timer, turn on the projector and adjust the volume, the Lullaby from MyBaby could be a good choice if you are looking for a unit that does more than just produce noise.

The Lullaby plays your choice of six different sounds. Gentle rainfall, ocean waves and heartbeat noises are the natural options. If your baby prefers to fall asleep to a lullaby song, you have the choice of Twinkle, Twinkle Little Star, Rock-A-Bye Baby or the Cradle Song by Brahms.

If your baby is more visual, they may find the projection feature soothing. Three image collections contain three individual scenes each, for a total of nine images. The top of the unit easily lifts off and allows you to select one of the three collections by turning a dial. The Lullaby will then display each scene in a sequence.

The projector is located at the top of the unit and displays the directly images upward. If you want the image projected in a different angle, you may need to use some creativity to tilt the Lullaby. The projector will turn off after three hours.

The timer feature offers your choice of 15, 30, 45 or 60 minutes. The unit will also run indefinitely if the timer is not enabled so you can still let it play all night if you want.

Munchkin Nursery Projector and Sound System

Pros

  • The machine can be set to turn on in response to your child's voice
  • Sound, image, nightlight, volume and timer settings are clearly labeled and easy to select
  • Projector disk storage space on the back of the unit

Cons

  • This unit tends to have a somewhat shorter lifespan
  • No battery option

Whether you want a sound machine, soothing images or a nightlight for your baby’s room, the Nursery Projector and Sound System from Munchkin has you covered. Your choice of ten sounds and three projector disks give you a lot of options for customizing your settings.

Choose your favorite sound from one of four natural options or one of the six musical pieces. Natural sounds include heartbeat, ocean waves, rainfall and white noise. If your baby prefers music, you can choose from the lullaby options of Brahms’ Lullaby, Hush Little Baby or Rock-a-Bye Baby. If you would like to introduce a classical piece, you can choose a song by Mozart: Mozart Lullaby, Twinkle Twinkle and Eine Kleine Nachtmusik.

The Nursery Projector has a pivoting feature to project rotating images of the sky, sea or rainforest above your baby’s crib or on the wall. The light from the projector provides a gentle glow and could double as a nightlight. You also have the option to turn on the actual night light feature that can function independently and provide a soft blue light.

One of the most unique features on the Nursery Projector and Sound System is the voice-activation capability. When this feature is engaged, the unit will automatically turn on to your chosen settings if your child cries or talks. This could prove to be a real help if you are trying to encourage self-soothing skills in your child.

Project Nursery Sound Machine with Nightlight

Pros

  • This machine is really cute - kids will love it!
  • AC or battery power options with four batteries included
  • Multiple brightness settings

Cons

  • Controls can be somewhat difficult to use in the dark
  • No projection feature

This cute little sound machine has the look of a toy and can fit right in with a young child’s room decor.

This Sound Soother and Nightlight has six sound choices and three brightness levels. Control buttons are located on the bear’s belly in the front of the unit. The buttons are covered with a silicone panel, and each control is identified by a raised symbol. You can set your preferred volume with up/down buttons, and you can select your sound, brightness and timer settings by scrolling through the options on each key.

The six sound settings include waves, white noise, heartbeat, Twinkle Twinkle Little Star, Brahms’ lullaby and Mozart’s Eine Kleine Nachtmusik. The Soother will play all night or you can set the timer for the machine to turn off after 15, 30, 45 or 60 minutes.

One of this machine’s best features is its dual power capability. You have the option of plugging the Project Nursery sound machine into a standard outlet or using four AAA batteries. This allows you to put the machine anywhere in your baby’s room regardless of where the power outlets are, and this feature can be really helpful if your little one tends to pull on cords. The battery option also lets you easily use the machine on the go.

Homedics SoundSpa White Noise Sound Machine

Pros

  • Very effective at masking outside noise
  • Dual power option
  • Lightweight and easy to transport

Cons

  • Seems to have a tendency to have a short lifespan
  • Has an unsecured battery panel

At just six inches across, two inches high and weighing eight ounces, this compact sound machine is easy to transport and could be a good choice if your baby will be using it at their babysitter’s or grandparent’s house. The option to plug the SoundSpa into the wall or use four AA batteries adds to the portability factor.

Don’t let the small size fool you, though. This machine produces noise that is soothing, but it is definitely loud enough to drown out unwanted sounds. Choose white noise or one of five nature options: Ocean, Rain, Summer Night, Brook and Thunder. Your baby can enjoy the sounds all night or just while they fall asleep with a 15, 30 or 60 minute time limit.

All the controls are located on the SoundSpa’s top surface and are very easy to use. Each sound has its own push button, as does the timer function. A dial controls the on/off and volume functions.

Lifespan on this model does seem to be on the shorter side. Another potential concern is the lack of a screw-secured battery panel, so you may want to make sure to place the SoundSpa well out of your baby’s reach.

Big Red Rooster BRRC129

Pros

  • Great sound quality
  • This small unit travels well
  • Battery or AC powered

Cons

  • The buttons click when pushed and could bother a light sleeper
  • No projector or nightlight
  • Unsecured battery plate

The Big Red Rooster weighs 5.9 ounces and measures four inches across and stands less than three inches tall. Despite its truly tiny size, this machine produces a fantastic quality of sound and is very effective at blocking noise.

The Big Red Rooster plays a mixture of natural sounds and music. Both the heartbeat and the ocean choices feature high-quality, realistic sounds. White noise is another natural option. For music, choose lullaby, Twinkle, Twinkle Little Star or Rock-a-Bye Baby. A timer gives you 15-, 30- and 60- minute options, or you can let the Big Red Rooster play continuously.

All settings are controlled by push buttons on the top of the unit. One small gripe is that these buttons make a bit of a clicking sound when pushed and may slightly disturb a sleeping baby.

Power the Big Red Rooster with either three AA batteries or plug the unit into the wall. The battery option combined with the machine’s small size makes the Big Red Rooster a great traveler. The battery plate closes with a finger tab and does not have a securing screw, so placing the unit up high is probably a good idea.

Baby Shusher Sleep Miracle Soother

Image to follow

Pros

  • Produces loud, effective noise
  • Designed to be easily portable
  • Two batteries are included

Cons

  • No additional sounds or features
  • No continuous play option

The Baby Shusher stands out from the crowd with its rounded edges, unusual sound and its underlying philosophy.

The idea for this machine is based on the book, “Happiest Baby on the Block” by Dr. Harvey Karp. In the book, Dr. Karp explains why babies can’t resist the shushing sound that parents so instinctively make. Since no parent can shush forever, the Baby Shusher aims to provide an electronic version of the human sound. This noise is the only sound option available, but the smooth audio loop has an undeniably calming tone.

The Baby Shusher differs from most other sound machines in the fact that it is meant to be used when your baby is upset and crying. Play the Shusher at a loud volume to act as a distraction, then turn the volume down as your baby’s crying diminishes and they drift off to sleep.

With the machine’s small size, battery power and rounded shape, taking the Baby Shusher along on your daily errands is convenient. You can easily pack the Shusher in the diaper bag or put it in the car seat or the stroller.

The Baby Shusher will play for your choice of 15 or 30 minutes. When it reaches that time limit, it will automatically turn off. The goal is to use the Shusher to help your baby calm down and fall asleep, but then allow them to learn to sleep in a more normal environment.

Buzbi Co. Soothing Sleep Owl

Pros

  • Offers a star projection feature and has a nice selection of sounds
  • Designed to be readily portable
  • Your child can also enjoy playing with this owl as a toy

Cons

  • No continuous play option
  • Need to be careful with the LED light

Not only is this owl from Buzbi Co. adorable, it also plays a good selection of sounds, has a calming star projector and can double as a stuffed toy.

Soothing Sleep Owl plays 10 gentle songs: American Patrol, Are You Sleeping, Baa Baa Black Sheep, Brahms Lullaby, Home Sweet Home, Hush Little Baby, London Bridge is Falling Down, Mary has a Little Lamb, Minuet and Oh My Darling. You can select an individual song or choose to play all the songs in a series. A heartbeat tone and a bird singing are two natural options.

Your baby can enjoy a relaxing light show with projected star images that softly change colors. However, the LED light source is very bright, so make sure to set up the owl in a place where the light will not shine directly in your baby’s eyes. The projection and sounds can be played together or independently.
Soothing Sleep Owl will play music or lights for 30 minutes before turning off automatically. If you want to have sound for a longer period, you will need to restart the machine manually.

Battery power and a hanging loop with Velcro closure make taking the Soothing Sleep Owl wherever you need to go a snap. You can easily attach the machine to your baby’s stroller or car seat to play sounds or lights on the move.

Four buttons on the owl’s front control lights, volume, sound selection and power. The electronic box is removable, allowing you to hand wash the plush fabric if it gets dirty.
